Safety, Compliance and Pharmacokinetics of Estetrol Monohydrate/Drospirenone 15/3 mg in Post-menarchal Female Adolescents
A Multicenter, Open-label, Single-Arm Study to Evaluate the Safety, Compliance and Pharmacokinetics Associated With the Use of a Combined Oral Contraceptive Containing 15 mg Estetrol Monohydrate and 3 mg Drospirenone in Post-menarchal Female Adolescents for 6 Cycles
Study Overview
Detailed Description
This is a Phase 3, open-label, non-controlled study in healthy post-menarchal female participants who will be enrolled to receive once daily E4/DRSP 15/3 mg for six (6) 28-day cycles in a 24/4-day regimen (i.e. 24 days of active tablets followed by 4 days of placebo tablets [4-day hormone-free interval]). The study will include 6 visits:
At screening visit (Visit 1), informed consent will be signed by the participants and their parent(s) or legal representative(s) and the screening procedures will be performed. The site will also complete an Eligibility confirmation phone call to the participant after Visit 1. During the enrollment visit (Visit 2, between Days 12 and 19 of the pre-treatment cycle), eligibility criteria will be reviewed and the participant participation will be confirmed. Participants will be trained in the use of an electronic diary and will receive the study drug. A follow-up call will be performed after Visit 2, within 7 days following the first investigational product intake. Afterwards, the participants will attend 3 on-treatment visits at the clinical site [between Days 14 and 21 of the Cycle 1(Visit 3), Cycle 3 (Visit 4), and Cycle 6 (Visit 5)] and one visit after end of Cycle 6 (Visit 6).
For participants who consent to participate in a pharmacokinetics sub-study, blood samples for this sub-study will be taken at Visit 3 and Visit 5.
Adverse events will be followed throughout the study.

---|---|---|
Number of participants with treatment-emergent adverse events
Time Frame: From Cycle 1 to end of study (between Days 16 and 23 of Cycle 7) (each cycle is 28 days)
|
Treatment emergent adverse events (TEAEs) are those adverse events occurring from time point of first ingestion of the investigational product until last visit or any event already present that worsens in either intensity or frequency following exposure to the treatment.

|
Treatment emergent adverse events (TEAEs) are those adverse events occurring from time point of first ingestion of the investigational product until last visit or any event already present that worsens in either intensity or frequency following exposure to the treatment. The causality of TEAEs (related or not related) is based on the following considerations: associative connections (time and/or place), pharmacological explanations, previous knowledge of the drug, presence of characteristic clinical or pathological phenomena, exclusion of other causes, and/or absence of alternative explanations. |

[Estonia-specific: the percentage of overall compliance is calculated as the ratio of the total number of pills taken across all cycles based on the daily response values entered by the participant in the e-diary and the number of pills expected to be taken from the start date of cycle 1 until the day of the last dose.] |
